-# THIS VERSION IS WORK IN PROGRESS!!!

-# BUGS MAY BE STILL PRESENT!!!
+  📄️ Instructions 📄
+</h2>
+
+### 📋 Prerequisites
+KIAUH is a script that assists you in installing Klipper on a Linux operating system that has
+already been flashed to your Raspberry Pi's (or other SBC's) SD card. As a result, you must ensure
+that you have a functional Linux system on hand. `Raspberry Pi OS Lite (either 32bit or 64bit)` is a recommended Linux image
+if you are using a Raspberry Pi. The [official Raspberry Pi Imager](https://www.raspberrypi.com/software/)
+is the simplest way to flash an image like this to an SD card.
+
+* Once you have downloaded, installed and launched the Raspberry Pi Imager,
+select `Choose OS -> Raspberry Pi OS (other)`: \
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager1.png" alt="KIAUH logo" height="350">
+</p>
+
+* Then select `Raspberry Pi OS Lite (32bit)` (or 64bit if you want to use that instead):
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager2.png" alt="KIAUH logo" height="350">
+</p>
+
+* Back in the Raspberry Pi Imager's main menu, select the corresponding SD card to which
+you want to flash the image.
+
+* Make sure to go into the Advanced Option (the cog icon in the lower left corner of the main menu)
+and enable SSH and configure Wi-Fi.
+
+* If you need more help for using the Raspberry Pi Imager, please visit the [official documentation](https://www.raspberrypi.com/documentation/computers/getting-started.html).
+
+These steps **only** apply if you are actually using a Raspberry Pi. In case you want
+to use a different SBC (like an Orange Pi or any other Pi derivates), please look up on how to get an appropriate Linux image flashed
+to the SD card before proceeding further (usually done with Balena Etcher in those cases). Also make sure that KIAUH will be able to run
+and operate on the Linux Distribution you are going to flash. You likely will have the most success with
+distributions based on Debian 11 Bullseye. Read the notes further down below in this document.
+
+### 💾 Download and use KIAUH
+**📢 Disclaimer: Usage of this script happens at your own risk!**
+
+* **Step 1:** \
+To download this script, it is necessary to have git installed. If you don't have git already installed, or if you are unsure, run the following command:
+```shell
+sudo apt-get update && sudo apt-get install git -y
+```
+
+* **Step 2:** \
+Once git is installed, use the following command to download KIAUH into your home-directory:
+
+```shell
+cd ~ && git clone https://github.com/dw-0/kiauh.git
+```
+
+* **Step 3:** \
+Finally, start KIAUH by running the next command:
+
+```shell
+./kiauh/kiauh.sh
+```
+
+* **Step 4:** \
+You should now find yourself in the main menu of KIAUH. You will see several actions to choose from depending
+on what you want to do. To choose an action, simply type the corresponding number into the "Perform action"
+prompt and confirm by hitting ENTER.

+
+## 📄 使用说明
+
+### 📋 系统要求
+KIAUH 是一个帮助您在 Linux 系统上安装 Klipper 的脚本工具，
+它需要一个已经写入树莓派（或其他单板计算机）SD 卡的 Linux 系统。
+如果您使用树莓派，推荐使用 `Raspberry Pi OS Lite (32位或64位)` 系统镜像。
+[官方 Raspberry Pi Imager](https://www.raspberrypi.com/software/) 是将此类镜像写入 SD 卡的最简单方式。
+
+* 下载、安装并启动 Raspberry Pi Imager 后，
+选择 `Choose OS -> Raspberry Pi OS (other)`:
+
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager1.png" alt="KIAUH logo" height="350">
+</p>
+
+* 然后选择 `Raspberry Pi OS Lite (32位)` (或如果您想使用64位版本):
+
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager2.png" alt="KIAUH logo" height="350">
+</p>
+
+* 返回 Raspberry Pi Imager 主界面，选择对应的 SD 卡作为写入目标。
+
+* 确保点击左下角的齿轮图标（在主菜单中）
+启用 SSH 并配置 Wi-Fi。
+
+* 如果您需要更多关于使用 Raspberry Pi Imager 的帮助，请访问 [官方文档](https://www.raspberrypi.com/documentation/computers/getting-started.html)。
+
+这些步骤**仅适用于**您实际使用树莓派的情况。如果您想使用其他单板计算机（如香橙派或其他 Pi 衍生产品），
+请查找如何将合适的 Linux 镜像写入 SD 卡（通常使用 Balena Etcher）。
+同时确保 KIAUH 能够在您要安装的 Linux 发行版上运行。
+您在使用基于 Debian 11 Bullseye 的系统时可能会获得最佳体验。
+请阅读本文档下方的注意事项。
+
+### 💾 下载并使用 KIAUH
+
+**📢 免责声明：使用此脚本的风险由您自行承担！**
+
+* **第一步：**
+要下载此脚本，需要先安装 git。
+如果您不确定是否已安装 git，请运行以下命令：
+```shell
+sudo apt-get update && sudo apt-get install git -y
+```
+
+* **第二步：**
+安装完 git 后，
+使用以下命令将 KIAUH 下载到您的主目录：
+
+```shell
+cd ~ && git clone https://github.com/dw-0/kiauh.git
+```
+
+* **第三步：**
+最后，通过运行以下命令启动 KIAUH：
+
+```shell
+./kiauh/kiauh.sh
+```
+
+* **第四步：**
+您现在应该会看到 KIAUH 的主菜单。
+根据您的选择，
+您会看到几个可选操作。
+要选择某个操作，只需在 "Perform action" 提示后输入对应的数字并按回车键确认。
+
+## ❗ 注意事项
+
+### **📋 请查看 [更新日志](docs/changelog.md) 以了解可能的重要更新！**
+
+- 主要在 Raspberry Pi OS Lite (Debian 10 Buster / Debian 11 Bullseye) 上测试
+    - 其他基于 Debian 的发行版（如 Ubuntu 20 到 22）也可能正常工作
+    - 据报告在 Armbian 上也可用，但未进行详细测试
+- 在使用此脚本的过程中，
+您会被要求输入 sudo 密码。
+因为有几个功能需要 sudo 权限。

+## Changelog
+
+This document covers possible important changes to KIAUH.
+
+### 2024-08-31 (v6.0.0-alpha.1)
+Long time no see, but here we are again!
+A lot has happened in the background, but now it is time to take it out into the wild.
+
+#### KIAUH has now reached version 6! Well, at least in an alpha state...
+
+The project has seen a complete rewrite of the script from scratch in Python.
+It requires Python 3.8 or newer to run. Because this update is still in an alpha state, bugs may or will occur.
+During startup, you will be asked if you want to start the new version 6 or the old version 5.
+As long as version 6 is in a pre-release state, version 5 will still be available. If there are any critical issues
+with the new version that were overlooked, you can always switch back to the old version.
+
+In case you selected not to get asked about which version to start (option 3 or 4 in the startup dialog) and you want to
+revert that decision, you will find a line called `version_to_launch=` within the `.kiauh.ini` file in your home directory.
+Just delete that line, save the file and restart KIAUH. KIAUH will then ask you again which version you want to start.
+
+Here is a list of the most important changes to KIAUH in regard to version 6:
+- The majority of features available in KIAUH v5 are still available; they just got migrated from Bash to Python.
+- It is now possible to add new/remove instances to/from existing multi-instance installations of Klipper and Moonraker
+- KIAUH now has an Extension-System. This allows contributors to add new installers to KIAUH without having to modify the main script.
+    - You will now find some of the features that were previously available in the Installer-Menu in the Extensions-Menu.
+    - The current extensions are:
+        - G-Code Shell Command (previously found in the Advanced-Menu)
+        - Mainsail Theme Installer (previously found in the Advanced-Menu)
+        - Klipper-Backup (new in v6!)
+        - Moonraker Telegram Bot (previously found in the Installer-Menu)
+        - PrettyGCode for Klipper (previously found in the Installer-Menu)
+        - Obico for Klipper (previously found in the Installer-Menu)
+    - The following additional extensions are planned, but not yet available:
+        - Spoolman (available in v5 in the Installer-Menu)
+        - OctoApp (available in v5 in the Installer-Menu)
+- KIAUH has its own config file now
+    - The file has some default values for the currently supported options
+    - There might be more options in the future
+    - It is located in KIAUH's root directory and is called `default.kiauh.cfg`
+        - DO NOT EDIT the default file directly, instead make a copy of it and call it `kiauh.cfg`
+        - Settings changed via the Advanced-Menu will be written to the `kiauh.cfg`
+- Support for OctoPrint was removed
+
+Feel free to give version 6 a try and report any bugs or issues you encounter! Every feedback is appreciated.
+
+### 2023-06-17
+KIAUH has now added support for installing Mobileraker's companion!
+Mobileraker is a free and Open Source Android and iOS App for Klipper, utilizing the Moonraker API, allowing you
+to control your printer. Thank you to [Clon1998](https://github.com/Clon1998) for adding this feature!
+
+### 2023-02-03
+The installer for MJPG-Streamer got replaced by crowsnest. It is an improved webcam service, utilizing ustreamer.
+Please have a look here for additional info about crowsnest and how to configure it: https://github.com/mainsail-crew/crowsnest \
+It's unsure if the previous MJPG-Streamer installer will be updated and make its way back into KIAUH.
+A big thanks to [KwadFan](https://github.com/KwadFan) for writing the crowsnest implementation.
+
+### 2022-10-31
+Some functions got updated, though not all of them.
+
+The following functions are still currently unavailable:
+- Installation of: MJPG-Streamer
+- All backup functions and the Log-Upload
+
+### 2022-10-20
+KIAUH has now reached major version 5 !
+
+Recently Moonraker introduced some changes which makes it necessary to change the folder structure of printer setups.
+If you are interested in the details, check out this PR: https://github.com/Arksine/moonraker/pull/491 \
+Although Moonraker has some mechanics available to migrate existing setups to the new file structure with the use of symlinks, fresh and clean installs
+should be considered.
+
+The version jump of KIAUH to v5 is a breaking change due to those major changes! That means v4 and v5 are not compatible with each other!
+This is also the reason why you will currently be greeted by a yellow notification in the main menu of KIAUH leading to this changelog.
+I decided to disable a few functions of the script and focus on releasing the required changes to the core components of this script.
+I will work on updating the other parts of the script piece by piece during the next days/weeks.
+So I am already sorry in advance if one of your desired components you wanted to install or use temporarily cannot be installed or used right now.
+
+The following functions are currently unavailable:
+- Installation of: KlipperScreen, Obico, Octoprint, MJPG-Streamer, Telegram Bot and PrettyGCode
+- All backup functions and the Log-Upload
+
+**So what is working?**\
+Installation of Klipper, Moonraker, Mainsail and Fluidd. Both, single and multi-instance setups work!\
+As already said, the rest will follow in the near future. Updating and removal of already installed components should continue to work.
+
+**What was removed?**\
+The option to change Klippers configuration directory got removed. From now on it will not be possible anymore to change
+the configuration directory from within KIAUH and the new filestructure is enforced.
+
+**What if I don't have an existing Klipper/Moonraker install right now?**\
+Nothing important to think about, install Klipper and Moonraker. KIAUH will install both of them with the new filestructure.
+
+**What if I have an existing Klipper/Moonraker install?**\
+First of all: Backups! Please copy all of your config files and the Moonraker database (it is a hidden folder, usually `~/.moonraker_database`) to a safe location.
+After that, uninstall Klipper and Moonraker with KIAUH. You can then proceed and re-install both of them with KIAUH again. It is important that you are on KIAUH v5 for that!
+Once everything is installed again, you need to manually copy your configuration files from the old `~/klipper_config` folder to the new `~/printer_data/config` folder.
+Previous, by Moonraker created symlinks to folder of the old filestructure will not work anymore, you need to move the files to their new location now!
+Do the same with the two files inside of `~/.moonraker_database`. Move/copy them into `~/printer_data/database`. If `~/printer_data/database` is already populated with a `data.mdb` and `lock.mdb`
+delete them or simply overwrite them. Nothing should be lost as those should be empty database files. Anyway, you made backups, right?
+You can now proceed and restart Moonraker. Either from within Mainsail or Fluidd, or use SSH and execute `sudo systemctl restart moonraker`.
+If everything went smooth, you should be good to go again. If you see some Moonraker warnings about deprecated options in the `moonraker.conf`, go ahead and resolve them.
+I will not cover them in detail here. A good source is the Moonraker documentation: https://moonraker.readthedocs.io/en/latest/configuration/
+
+**What if I have an existing Klipper/Moonraker multi-instance install?**\
+Pretty much the same steps that are required for single instance installs apply to multi-instance setups. So please go ahead and read the previous paragraph if you didn't already.
+Make backups of everything first. Then remove and install the desired amount of Klipper and Moonraker instances again.
+Now you need to move all config and database files to their new locations.\
+Example with an instance called `printer_1`:\
+The config files go from `~/klipper_config/printer_1` to `~/printer_1_data/config`.
+The database files go from `~/.moonraker_database_1` to `~/printer_1_data/database`.
+Now restart all Moonraker services. You can restart all of them at once if you launch KIAUH, and in the main menu type `restart moonraker` and hit Enter.
+
+I hope I have covered the most important things. In case you need further support, the official Klipper Discord is a good place to ask for help.
+
+### 2022-08-15
+Support for "Obico for Klipper" was added! Huge thanks to [kennethjiang](https://github.com/kennethjiang) for helping me with the implementation!
+
+### 2022-05-29
+KIAUH has now reached major version 4 !
+* feat: Klipper can be installed under Python3 (still considered as experimental)
+* feat: Klipper can be installed from custom repositories / inofficial forks
+* feat: Custom instance name for multi instance installations of Klipper
+  * Any other multi instance will share the same name given to the corresponding Klipper instance
+  * E.g. klipper-voron2 -> moonraker-voron2 -> moonraker-telegram-bot-voron2
+* feat: Option to allow installation of / updating to unstable Mainsail and Fluidd versions
+  * by default only stable versions get installed/updated
+* feat: Multi-Instance OctoPrint installations now each have their own virtual python environment
+  * allows independent installation of plugins for each instance
+* feat: Implementing the use of shellcheck during development
+* feat: Implementing a simple logging mechanic
+* feat: Log-upload function now also allows uploading other logfiles (kiauh.log, webcamd.log etc.)
+* feat: added several new help dialogs which try to explain various functions
+* fix: During Klipper installation, checks for group membership of `tty` and `dialout` are made
+* refactor: rework of the settings menu for better control the new KIAUH features
+* refactor: Support for DWC and DWC-for-Klipper has been removed
+* refactor: The backup before update settings were moved to the KIAUH settings menu
+* refactor: Switch branch function has been removed (was replaced by the custom Klipper repo feature)
+* refactor: The update manager sections for Mainsail, Fluidd and KlipperScreen were removed from the moonraker.conf template
+  * They will now be individually added during installation of the corresponding interface
+* refactor: The rollback function was reworked and now also allows rollbacks of Moonraker
+  * It now takes numerical inputs and reverts the corresponding repository by the given amount instead
+  * KIAUH does not save previous states to its config anymore like it did with the previous approach
+
+
+### 2022-01-29
+* Starting from the 28th of January, Moonraker can make use of PackageKit and PolicyKit.\
+More details on that can be found [here](
+https://github.com/Arksine/moonraker/issues/349) and [here](https://github.com/Arksine/moonraker/pull/346)
+* KIAUH will install Moonrakers PolicyKit rules by default when __installing__ Moonraker
+* KIAUH will also install Moonrakers PolicyKit rules when __updating__ Moonraker __via KIAUH__ as of now
+
+### 2021-12-30
+* Updated the doc for the usage of the [G-Code Shell Command Extension](docs/gcode_shell_command.md)
+* It became apparent, that some user groups are missing on some systems. A missing video group \
+membership for example caused issues when installing mjpg-streamer while not using the default pi user. \
+Other issues could occur when trying to flash an MCU on Debian or Ubuntu distributions where a user might not be part
+of the dialout group by default. A check for the tty group is also done. The tty group is needed for setting
+up a linux MCU (currently not yet supported by KIAUH).
+* There is an issue when trying to install Mainsail or Fluidd on Ubuntu 21.10. Permissions on that distro seem to have seen a rework
+ in comparison to 20.04 and users will be greeted with an "Error 403 - Permission denied" message after installing one of Klippers webinterfaces.
+I still have to figure out a viable solution for that.
+
+### 2021-09-28
+* New Feature! Added an installer for the Telegram Bot for Moonraker by [nlef](https://github.com/nlef).
+Checkout his project! Remember to report all issues and/or bugs regarding that project in its corresponding repo and not here 😛.\
+You can find it here: https://github.com/nlef/moonraker-telegram-bot
+
+### 2021-09-24
+* The flashing function got adjusted a bit. It is now possible to also flash controllers which are connected over UART and thus accessible via `/dev/ttyAMA0`. You now have to select a connection methop prior flashing which is either USB or UART.
+* Due to several requests over time I have now created a Ko-fi account for those who want to support this project and my work with a small donation. Many thanks in advance to all future donors. You can support me on Ko-fi with this link: https://ko-fi.com/th33xitus
+* As usual, if you find any bugs or issues please report them. I tested the little rework i did with the hardware i have available and haven't encountered any malfunctions of flashing them yet.
+
+### 2021-08-10
+* KIAUH now supports the installation of the "PrettyGCode for Klipper" GCode-Viewer created by [Kragrathea](https://github.com/Kragrathea)! Installation, updating and removal are possible with KIAUH. For more details to this cool piece of software, please have a look here: https://github.com/Kragrathea/pgcode
+
+### 2021-07-10
+* The NGINX configuration files got updated to be in sync with MainsailOS and FluiddPi. Issues with the NGINX service not starting up due to wrong configuration should be resolved now. To get the updated configuration files, please remove Moonraker and Mainsail / Fluidd with KIAUH first and then re-install it. An automated file check for those configuration files might follow in the future which then automates updating those files if there were important changes.
+
+* The default `moonraker.conf` was updated to reflect the recent changes to the update manager section. The update channel is set to `dev`.
+
+### 2021-06-29
+* KIAUH will now patch the new `log_path` to existing moonraker.conf files when updating Moonraker and the entry is missing. Before that, it was necessary that the user provided that path manually to make Fluidd display the logfiles in its interface. This issue should be resolved now.
+
+### 2021-06-15
+
+* Moonraker introduced an optional `log_path` which clients can make use of to show log files located in that folder to their users. More info here: https://github.com/Arksine/moonraker/commit/829b3a4ee80579af35dd64a37ccc092a1f67682a \
+Client developers agreed upon using `~/klipper_logs` as the new default log path.\
+That means, from now on, Klipper and Moonraker services installed with KIAUH will place their logfiles in that mentioned folder.
+* Additionally, KIAUH will now detect Klipper and Moonraker systemd services that still use the old default location of `/tmp/<service>.log` and will update them next time the user updates Klipper and/or Moonraker with the KIAUH update function.
+* Additional symlinks for the following logfiles will get created along those update procedures to make them accessible through the webinterface once its supported:
+    - webcamd.log
+    - mainsail-access.log
+    - mainsail-error.log
+    - fluidd-access.log
+    - fluidd-error.log
+* For MainsailOS and FluiddPi users:\
+MainsailOS and FluiddPi will switch the shipped Klipper service from SysVinit to systemd probably with their next release. KIAUH can already help migrate older MainsailOS (0.4.0 and below) and FluiddPi (v1.13.0) releases to match their new service-, file- and folder-structure so you don't have to re-flash the SD-Card of your Raspberry Pi.\
+In detail here is what is going to happen when you use the new "CustomPiOS Migration Helper" from the Advanced Menu\
+`(Main Menu -> 4 -> Enter -> 10 -> Enter)` in a short summary:
+    * The Klipper SysVinit service will get replaced by a Klipper systemd service
+    * Klipper and Moonraker will use the new log-directory `~/klipper_logs`
+    * The webcamd service gets updated
+    * The webcamd script gets updated and moved from `/root/bin/webcamd` to `/usr/local/bin/webcamd`
+    * The NGINX `upstreams.conf` gets updated to be able to configure up to 4 webcams
+    * The `mainsail.txt` / `fluiddpi.txt` gets moved from `/boot` to `~/klipper_config` and renamed to `webcam.txt`
+    * Symlinks for the webcamd.log and various NGINX logs get created in `~/klipper_config`
+    * Configuration files for Klipper, Moonraker and webcamd get added to `/etc/logrotate.d`
+    * If they still exist, two lines will be removed from the mainsail.cfg or client_macros.cfg macro configurations:\
+    `SAVE_GCODE_STATE NAME=PAUSE_state` and `RESTORE_GCODE_STATE NAME=PAUSE_state`
+* **Please note:**\
+The "CustomPiOS Migration Helper" is intended to only work on "vanilla" MainsailOS and FluiddPi systems. Do not try to migrate a modified MainsailOS or FluiddPi system (for example if you already used KIAUH to re-install services or to set up a multi-instance installation for Klipper / Moonraker). This won't work.
+
+### 2021-01-31
+
+* **This is a big one... KIAUH v3.0 is out.**\
+With this update you can now install multiple instances of Klipper, Moonraker, Duet Web Control or Octoprint on the same Pi. This was quite a big rework of the whole script. So bugs can appear but with the help of some testers, i think there shouldn't be any critical ones anymore. In this regards thanks to @lixxbox and @zellneralex for testing.
+
+* Important changes to how installations are set up now: All components get installed as systemd services. Installation via init.d was dropped completely! This shouldn't affect you at all, since the common linux distributions like RaspberryPi OS or custom distributions like MainsailOS, FluiddPi or OctoPi support both ways of installing services. I just wanted to mention it here.
+
+* Now with KIAUH v3.0 and multi-instance installation capabilities, there are some things to point out. You will now need to tell KIAUH where your printers configurations are located when installing Klipper for the first time. Even though it is not recommended, you can change this location with the help of KIAUH and rewrite Klipper and Moonraker to use the new location.
+
+* When setting up a multi-instance system, the folder structure will only change slightly. The goal was to keep it as compatible as possible with the custom distributions like mainsailOS and FluiddPi. This should help converting a single-instance setup of mainsailOS/FluiddPi to a multi-instance setup in no time, but keeping single-instance backwards compatibility if needed at a later point in time.
+
+* The folder structure is as follows when setting up multi-instances:\
+Each printer instance will get its own folder within your configuration location. The decision to this specific structure was made to make it as painless and easy as possible to convert to a multi-instance setup.
+Here is an example:
+    ```shell
+    /home/<username>
+              └── klipper_config
+                  ├── printer_1
+                  │   ├── printer.cfg
+                  │   └── moonraker.conf
+                  ├── printer_2
+                  │   ├── printer.cfg
+                  │   └── moonraker.conf
+                  └── printer_n
+                      ├── printer.cfg
+                      └── moonraker.conf
+    ```
+* Also when setting up multi-instances of each service, the name of each service slightly changes.
+Each service gets its corresponding instance added to the service filename.
+
+    **This only applies to multi-instances! Single instance installations with KIAUH will keep their original names!**
+
+    Corresponding to the filetree example from above that would mean:
+    ```
+    Klipper services:
+            --> klipper-1.service
+            --> klipper-2.service
+            --> klipper-n.service
+
+    Moonraker services:
+            --> moonraker-1.service
+            --> moonraker-2.service
+            --> moonraker-n.service
+    ```
+* The same service file rules from above apply to OctoPrint even though only Klipper and Moonraker are shown in this example.
+
+* You can start, stop and restart all Klipper, Moonraker and OctoPrint instances from the KIAUH main menu. For doing this, just type "stop klipper", "start moonraker", "restart octoprint" and so on.
+
+* KIAUH v3.0 relocated its ini-file. It is now a hidden file in the users home-directory calles `.kiauh.ini`. This has the benefit of keeping all values in that file between possible re-installations of KIAUH. Otherwise that file would be lost.
+
+* The option of adding more trusted clients to the moonraker.conf file was dropped. Since you can edit this file right inside of Mainsail or Fluidd, only some basic entries are made which get you running.
+
+* I bet i have missed mentioning other stuff as well because it took me quite some time to re-write many functions. So i just hope you like the new version 😄

+* KIAUH now supports the installation, update and removal of [KlipperScreen](https://github.com/jordanruthe/KlipperScreen). This feature was was provided by [jordanruthe](https://github.com/jordanruthe)! Thank you!
+
+### 2020-11-18
+
+* Some changes to Fluidd caused a little rework on how KIAUH will install/update Fluidd from now on. Please see the [fluidd v1.0.0-rc0 release notes](https://github.com/cadriel/fluidd/releases/tag/v1.0.0-rc.0) for further information about what modifications to the moonraker.conf file exactly had to be done. In a nutshell, KIAUH will now always patch the required entries to the moonraker.conf if not already there.
+
+### 2020-10-30:
+
+* The user can now choose to install Klipper as a systemd service.
+
+* The Shell Command extension and `shell_command.py` got renamed to G-Code Shell Command extension and `gcode_shell_command.py`. In case the [pending PR](https://github.com/KevinOConnor/klipper/pull/2173) will be merged in the future, this was an early attempt to dodge possible incompatibilities. The [G-Code Shell Command docs](gcode_shell_command.md) has been updated accordingly.
+
+* The way how KIAUH interacts and writes to the users printer.cfg got changed. Usually KIAUH wrote everything directly into the printer.cfg. The way it will work from now on is, that a new file called `kiauh.cfg` will be created if there is something that needs to be written to the printer.cfg and everything gets written to `kiauh.cfg` instead. The only thing which then gets written to the users printer.cfg is `[include kiauh.cfg]`. This line will be located at the very top of the existing printer.cfg with a little comment as a note. The user can then decide to either keep the `kiauh.cfg` or take its content, places it into the printer.cfg directly and remove the `[include kiauh.cfg]`.
+
+* The `mainsail_macros.cfg` got renamed to `webui_macros.cfg`. Since Mainsail and Fluidd both use the same kind of pause, cancel and resume macros, a more generic name was chosen for the file containing the example macros one can choose to install when installing those webinterfaces.
+
+### 2020-10-10:
+
+* Support for changing the Klipper branch to the moonraker-dev branch from @Arksine has been dropped. Support for Moonraker has been merged into Klipper mainline a long time ago.
+
+* A new function is available from the main menu. You can now upload your log files to http://paste.c-net.org/ to share them for debugging purposes.
+
+### 2020-10-06:
+
+* Fluidd, a new Klipper interface got added to the list of available installers. At the same time some installation routines have changed or have seen some rework. Changes were made to the installation of NGINX configurations. A method was introduced to change the listen port of a webinterface configuration if there is already another webinterface listening on the default port (80).
+
+* At the moment, the Moonraker installer no longer asks you whether you want to install a web interface too. For now you therefore have to install them with their respective installers. Please report any bugs or issues you encounter.
+
+### 2020-09-17:
+
+* The dev-2.0 branch will be abandoned as of today. If you did a checkout to that branch in the past, you have to checkout back to master to receive updates.
+
+### 2020-09-12:
+
+* The old [dwc2-for-klipper](https://github.com/Stephan3/dwc2-for-klipper) won't be supported anymore!\
+The is a new, fully rewritten project available: [dwc2-for-klipper-socket](https://github.com/Stephan3/dwc2-for-klipper-socket).\
+The installer of this script also got rewritten to make use of that new project. You will not be able to install or remove the old [dwc2-for-klipper](https://github.com/Stephan3/dwc2-for-klipper) with KIAUH anymore if you updated KIAUH to the newest version.

+# G-Code Shell Command Extension
+
+### Creator of this extension is [Arksine](https://github.com/Arksine).
+
+This is a brief explanation of how to use the shell command extension for Klipper, which you can install with KIAUH.
+
+After installing the extension you can execute linux commands or even scripts from within Klipper with custom commands defined in your printer.cfg.
+
+#### How to configure a shell command:
+
+```shell
+# Runs a linux command or script from within klipper.  Note that sudo commands
+# that require password authentication are disallowed. All executable scripts
+# should include a shebang.
+# [gcode_shell_command my_shell_cmd]
+#command:
+#  The linux shell command/script to be executed.  This parameter must be
+#  provided
+#timeout: 2.
+#  The timeout in seconds until the command is forcably terminated.  Default
+#  is 2 seconds.
+#verbose: True
+#  If enabled, the command's output will be forwarded to the terminal.  Its
+#  recommended to set this to false for commands that my run in quick
+#  succession.  Default is True.
+```
+
+Once you have set up a shell command with the given parameters from above in your printer.cfg you can run the command as follows:
+`RUN_SHELL_COMMAND CMD=name`
+
+Example:
+
+```
+[gcode_shell_command hello_world]
+command: echo hello world
+timeout: 2.
+verbose: True
+```
+
+Execute with:
+`RUN_SHELL_COMMAND CMD=hello_world`
+
+### Passing parameters:
+As of commit [f231fa9](https://github.com/dw-0/kiauh/commit/f231fa9c69191f23277b4e3319f6b675bfa0ee42) it is also possible to pass optional parameters to a `gcode_shell_command`.
+The following short example shows storing the extruder temperature into a variable, passing that value with a parameter to a `gcode_shell_command`, which then, 
+once the gcode_macro runs and the gcode_shell_command gets called, executes the `script.sh`. The script then echoes a message to the console (if `verbose: True`) 
+and writes the value of the parameter into a textfile called `test.txt` located in the home directory.
+
+Content of the `gcode_shell_command` and the `gcode_macro`:
+```
+[gcode_shell_command print_to_file]
+command: sh /home/pi/klipper_config/script.sh
+timeout: 30.
+verbose: True
+
+[gcode_macro GET_TEMP]
+gcode:
+    {% set temp = printer.extruder.temperature %}
+    { action_respond_info("%s" % (temp)) }
+    RUN_SHELL_COMMAND CMD=print_to_file PARAMS={temp}
+```
+
+Content of `script.sh`:
+```shell
+#!/bin/sh
+
+echo "temp is: $1"
+echo "$1" >> "${HOME}/test.txt"
+```
+
+## Warning
+
+This extension may have a high potential for abuse if not used carefully! Also, depending on the command you execute, high system loads may occur and can cause system instabilities.
+Use this extension at your own risk and only if you know what you are doing!

+#

+#
+#camera_usb_options="-r 640x480 -f 10"
+
+### Additional webcam devices known to cause problems with -f
+#
+# Apparently there a some devices out there that with the current 
+# mjpg_streamer release do not support the -f parameter (for specifying 
+# the capturing framerate) and will just refuse to output an image if it 
+# is supplied.
+#
+# The webcam daemon will detect those devices by their USB Vendor and Product
+# ID and remove the -f parameter from the options provided to mjpg_streamer.
+#
+# By default, this is done for the following devices:

+#   Cubeternet GL-UPC822 UVC WebCam (1e4e:0102)
+#
+# Using the following option it is possible to add additional devices. If
+# your webcam happens to show above symptoms, try determining your cam's
